Title: An improved process and apparatus for making fuel briquettes
IPC: C10L5/22
Filed: 1922-05-16
Abstract: 202,386. Knight, J. S., and Hudson, H. May 16, 1922. Composition fuel briquettes are made by spraying from both sides a freely falling thin wide sheet of powdered fuel material with a binding agent such as waste sulphite liquor, and subjecting the impregnated material in masses to compression. The powdered material is delivered, after grinding and screening operations, to a feed hopper A from which it is fed at a uniform rate on to converging plates E by means of rotating cylinders B each having a filling and discharging opening C. On each side of a passage F sulphite liquor, pumped into chambers H surrounded by hot water or steam chambers L, issues from a row of nozzles I and is sprayed by compressed air from a row of jets J on to the falling fuel. The impregnated material passes through a screw conveyer to a roller press having recesses T; the formed briquettes are heated to about 350‹ C.

Title: A process for the production of trans -cyclohexane-1,4-dimethanol
IPC: C07C35/02
Filed: 1963-04-08
Abstract: A process for the production of trans-cyclohexane-1, 4-dimethanol comprises heating cis-cyclohexane-1, 4-dimethanol at temperatures from 180-220 DEG C. with metallic lithium or a lithium alcoholate preferably in an amount up to 2.5% by weight and subjecting the product to hydrolysis or alcoholysis e.g. with the same alcohol as that from which the lithium alcoholate is derived. The lithium alcoholate formed in the alcoholysis of the reaction product is separated and used again for the treatment of the cis-isomers. In an example cis-cyclohexane-1, 4-dimethanol and lithium metal are slowly heated in a nitrogen atmosphere on a bath at a temperature of 180 DEG C. for 2 hours.  After cooling, the reaction product is washed with acetone, boiled under reflux for 1 1/2 hours with 60 cc. of water, the aqueous solution of the trans-cyclohexane-1, 4-dimethanol formed was concentrated and the trans-isomer extracted with acetone.

Title: Improvements in or relating to transfer sheets, ribbons, tapes or the like and transfer compositions therefor
Inventor: POPIOLEK WLADISLAS
IPC: B41M5/10
Filed: 1958-05-02
Abstract: A waxless, or substantially waxless, pressureresponsive transfer composition comprises a thermoplastic high polymer, colouring matter, an organic compound having at least one functional group possessing a lone electron pair, a finely-divided inorganic filler and a nonvolatile, non-drying oil in which the polymer is substantially insoluble and which serves as a medium in which the colouring matter is dispersed and/or dissolved.  The organic compound and the filler are each present in such an amount as to provide a composition which, when applied in a volatile organic liquid to a sheet, ribbon, tape or the like, provides, after evaporation of the volatile organic liquid, a transfer layer which permits an image-forming material comprising colouring matter and oil to be transferred to an image-receiving surface on application of pressure.  The thermoplastic high polymer is a cellulose ester or mixed ester, an acrylic polymer or copolymer, or a polymer or copolymer of an aromatic vinyl compound in which the degree of polymerization is such that the polymer is capable of forming a film.  It must be soluble in a volatile organic liquid boiling below 130 DEG C.  Examples are cellulose acetate, propionate and butyrate and their mixed esters, polyalkyl acrylates and methacrylates, polystyrene and styrene-acrylonitrile and styrene-methyl methacrylate copolymers. The organic compound having the lone electron pair may be volatile, or non-volatile, examples are ethanol, acetone, propylamine, ethyl acetate, acetamide, acetic acid, benzoquinone, stearylamine, and oleic acid.  It must be compatible with the other components of the composition, and with the composition as a whole; it must not be of a drying nature.  The volatile organic liquid must boil below 130 DEG C., examples are methylene chloride and mixtures of methylene chloride and benzene. The oil may be mineral or castor oil, and in the latter case may serve also as the organic compound having the lone electron pair. The colouring matter may be soluble or insoluble in the oil, examples are carbon black, "Fanal" (Registered Trade Mark), violet, reflex blue, victoria pure blue, and Milori blue.  Certain silicate pigments, e.g. ultramarine, may serve as both pigment and filler, or the filler may be china clay.  The composition may also include a surface-active agent and/or a plasticizer for the high polymer. The composition may be prepared by first dissolving the thermoplastic high polymer in the volatile organic liquid, and placing approximately half of this in a ball mill with the other ingredients. After grinding to a good dispersion, it is mixed with the rest of the polymer solution.  Specifications 780,492 and 876,854 are referred to.

Title: Improvements in or relating to synchronous motor clocks and synchronous motor clock systems
IPC: G04C15/00
Filed: 1937-05-27
Abstract: 477,256. Electric clock systems. SIEMENS & HALSKE AKT.-GES. May 27, 1937, No. 14730. Addition to 466,692. [Class 139] An automatic control device for the synchronous motor clock system described in the parent Specification, wherein auxiliary clocks are each driven through a differential gear by two synchronous motors acting in opposite senses, comprises a differential gear driven by a synchronous motor clock and, through a slip coupling, by the precision clock controlling the system ; the planet wheel, which is arranged to actuate relays for stopping one or other of the synchronous motors when displaced, normally remaining in a fixed plane. The precision clock HU controls the speed of the motor M driving the A.C. generator G supplying current to the auxiliary clocks u<1>, u<2>, u<3>, &c., and also drives through a slip coupling 9 and suitable gearing a wheel 3 of a differential gear, the other wheel 2 being driven in the opposite direction by a synchronous motor clock u so that the axis of the planet wheel 1 normally remains stationary. Any change in the basic time of the auxiliary clocks is made by rotating the indicator 11 to displace the wheel 3, and move a contact arm 13 off an insulated portion 14 to one of the contacts 15, 16 connected with switching relays S<1>, S<2> so as to switch out the corresponding synchronous motors of all the auxiliary clocks including the clock u which, consequently, gives the wheel 2 an additional corrective rotation and brings the arm 13 back to its normal position. To enable all the auxiliary clocks to be corrected at a predetermined time by the means described in the parent Specification, the appropriate driving motor of each auxiliary clock is switched off shortly beforehand to cause the hands of the clocks to move forward with increased speed.
